OONVEYEB CLEAT.

Application filed June 10, 1826. Serial No. 114,885.

This invention relates to improvements in conveyer cleats of that typearticularly used on chain drag conveyers or sawdust and refuse in sawmills and like places.

The object of the invention is to produce a sectional cleat for thepurpose which can be easily and quickly assembled on the chain and theresecured in position. A further object is to produce a cleat which, whenso assembled on the chain, is so constructed that the sectional partsmay be accurately and rigidly fastened together so as to be in effect asingle unitary structure. This will insure long life to the cleat andrender its operation 16 properly effective.

A further object of the invention to produce a simple and inexpensivedevice and yet one which will be exceedingly effective for the purposefor which it is designed.

These objects I accomplish by means of such structure and relativearrangement of parts as will fully appear by a perusal of the followingspecification and claims.

In the drawings similar characters of reference indicate correspondingparts in the several views:

Fi 1 is a top 'lan view of a section of the rag chain an ,cleats as theyappear in operative assembled position in the drag trough.

Fig. 2 is a side elevation of the sectional parts of a single cleatshowing them in position assumed as the are being assembled into thechain, the c ain link being shown in section.

Fig. 3 is a top plan view of the bottom section of the cleat.

Fig. 4 is a longitudinal vertical section throu h a completely assembledcleat.

Re erring now more particularly to the characters of reference on thedrawings, the numeral 1 designates the drag chain link into which thesectional cleat is assembled.

The cleat comprises two complementary members consisting of a bottomsection 2 and a to section 3. The bottom section 2 is provided with atransverse recess 4 in its under face to receive one side of the link 1.The opposite side of the section 2 is cut away as at 5 in a planesurface to a point just short of the center line of the cleat where itraises slightly to form a shelf 6 at the center of the cleat, from whichshelf is a curved portion 7 rising upwardly in a substantially 90 degreeare to the top surface of the cleat.

The cut out portion 5 as well as the shelf 6 and the top roper of thecleat section 2 is full surfaced from edge to edge of the cleat section.

In the face of the shelf 6 is a cut-out recess 00 8 and in the face ofthe surface of the cut away portion 5 adjacent the front face of thecleat is another cut out recess 9.

The cleat section 3 is made as a com lement to the section 2 to make thecomp ete cleat and has a cut away portion 10 to fit over the shelf 6; alug 11 to fit the recess 8; 3. lug 12 to fit the recess 9; and a curvedend 13 to fit the curved portion 7. Immediately ad'acent the curved end13 is a recess 14, a apted, when the sections are assembled, to beparallel with and in the same vertical plane as the recess 4 so that thecurved end of the sections 3 may be rotated into engagement with thelink 1 and com- 7 plete the cleat tied into the link. Both sides of thesection 3 have full surfaces from edge to edge, so that when thesections are assembled the under surface lies flush with the surface ofthe cut away portion 5 and the lugs 11 and 12 fit snugly into therecesses 8 and 9 to definitely and positively fix the proper relativeposition of the two complementary sections and make a substantiallysolid and unitary cleat when the parts are $5 riveted together, as willnow be explained. In adjacent outer ends of the sections 2 and 3 arealined rivet holes 15 and 16 respectively. When the parts are assembleda rivet 17 is set through these holes and secures the parts together asa unit.

After the sections are riveted together the flat contacting surfacebetween the two and the abutting shoulders formed between the upraisedshelf 6 and the cut out portion 1') together with the spaced lugs 11 and12 fit ting closely into the recesses 8 and 9 positively prevent eithertransverse or longitudinal loose movement between the sections 2 and 3,and hence shifting of parts and consequent wear and inefficientoperation is completel avoided.

From t e foregoing description it will be readily seen that I haveproduced such a device as substantially fulfills the objects of theinvention as set forth herein.

While this specification sets forth in detail the present and preferredconstruction of the device, still in practice such deviations from suchdetail may be resorted to as do not form a departure from the spirit ofthe invention, as defined by the appended claims.

Having thus described my invention what I claim as new and useful anddesire to secure by Letters Patent is:

1. A conveyer cleat comprising two C0111- plementary cleat sections onesection having a flat under surface rovided with a transverse grooveinterme iate its ends and a fiat surfaced cut away portion in its upperside extending from one end to a oint short of the groove, an upraisedshel at the inner end of the cut away portion and crossing the plane ofthe roove and curving in 'an arc to the top surface of the cleat; theother section having a flat surface to lay against the flat surface ofthe cut away portion of the first section, a cut out portion to seatover the shelf, a curved end {0 engage the curve of the shelf, the innerend of said second section being provided with a transverse groovearranged to lie parallel with and in the same vertical plane as thetransverse groove in the first section when the two are assembledtoether; and means to fasten the sections rigi lyjogether.

2. A conve er cleat comprising two complementary c eat sections, onehaving a fiat under surface rovided with a transverse groove intermeiate its ends and having a at surfaced cut away portion in its upperside terminating short of the transverse center .line of the cleatsection, an upraised shelf at the inner end of the cut away portion andcrossing the center line of the cleat section and curving in an arc tothe top surface of the cleat; the cut away portion and the shelf eachhaving a recess in its surface; the other section having a flat surfaceto lay against the fiat surface of the cut away portion of the firstsection, a cut out portion to fit over said shelf, a curved end toengage the curve of the shelf, lugs to fit into said recesses, the innerend of such second section being provided with a transverse groovearranged to lie parallel with and in the same vertical plane as thegroove in the first section when the two are assembled together; andmeans to fasten the two sections rigidly to ether.

11 testimony. whereof I affix my signature.
